Toroidal deflection winding for cathode ray tube having in-line guns, wide deflection angle and large screen

摘要

A toroidal vertical deflection winding for use with a yoke designed for a large screen, color cathode ray tube having in-line guns and a wide deflection angle, the winding constructed to achieve deflection and self-convergence of the electron beams over the entire screen of the tube without coma effect, the winding comprised of a frustrum-shaped magnetic core with three quarter-section primary clusters of toroidally wound conductors formed thereon in predetermined arcs, the conductors of at least one of said primary clusters being non-radially wound, said conductors being positioned generally geometrically parallel to each other and said primary clusters having substantially predetermined numerical conductor relationship.
